Quebrada de las Conchas, also known as the Cafayate Gorge, is a stunning natural canyon located in the Salta Province of Argentina. It is a protected natural reserve that stretches for about 20 kilometers along National Route 68, between the towns of Cafayate and Salta.

The colorful formations of the canyon are the result of millions of years of erosion from wind and water, and the area is known for its striking red, orange, and yellow rock formations, which provide a unique backdrop for visitors. Some of the most famous formations within the canyon include El Obelisco, Los Castillos, El Anfiteatro, La Garganta del Diablo, and El Sapo.

Quebrada de las Conchas is also home to a variety of flora and fauna, including the cardones, a type of cactus that can grow up to 6 meters tall, and the vizcachas, a small rabbit-like animal.

Visitors can explore the area on foot or by car, and there are several viewpoints and trails throughout the park. The most popular way to experience the canyon is by taking a guided tour from Cafayate, which includes stops at some of the most iconic formations in the canyon. It's also possible to combine a visit to Quebrada de las Conchas with a visit to the nearby vineyards and wineries in the region, which are known for producing some of the best wines in Argentina.
